Synthesis of Yolk/Shell Fe3O4@Poly(ionic liquid)s-Derived Nitrogen doped Mesoporous Carbon Materials and as Support for Nickel Catalysts

The fabrication of yolk/shell spheres consisting of a movable magnetic core, a poly(ionic liquid)s-derived porous carbon shell, and plenty of tiny nickel nanoparticles confined within the porous shell is reported. The as-synthesized carbon products are graphitic, mesoporous, and highly conductive, as proven by XRD and TEM characterizations. Without demand for any template, this method is facile and easy to scale up and might contribute to the wide range of applications of carbon nanostructures. The ensuing catalyst has been employed for the tandem dehydrogenation of of sodium bororhydride and hydrogenation of several nitro/nitrile compounds in aqueous media which resulted high yields and desired selectivity with a very low content of the catalyst
